Description

  The present invention relates to a disk drive device having a printing function for printing desired characters or pictures on a label surface of a disk such as a CD or a DVD.

  In recent years, disk-shaped recording media such as CDs and DVDs (hereinafter simply referred to as disks) have been widely used, and various types of disk drive devices for driving these disks are also available. It has come to be offered. There is a demand for a disk drive device from a read-only device that only reproduces pre-recorded information to a recording / reproduction device that can arbitrarily record (write) information that the user wants to save on the disk. There is a transition situation.

  By the way, generally a disc in a recordable blank state has the same appearance, and the content of information recorded by the user cannot be confirmed. Therefore, there are many cases where the user writes down the information content recorded by the user on the label side of the disc (the side opposite to the information recording side for recording information). However, handwriting every time a recording disk is created is troublesome, and there are problems such as poor appearance when characters on the disk surface are handwritten.

  Therefore, recently, a disk drive device having a function of printing on the label surface of the disk has been provided. Such a disk drive device is very convenient because information can be recorded on the disk and characters or the like that can confirm the recorded contents can be printed on the label surface. Patent Document 1 discloses an optical disk information recording apparatus having such a printing function. This apparatus performs label printing by ejecting ink particles from an ink jet type printer head arranged opposite to the label surface of the disk while rotating the disk.

Japanese Patent Application Laid-Open No. 5-280505

  The apparatus disclosed in Patent Document 1 is formed so as to perform printing on the label surface after the writing on the information recording surface of the disc is completed. However, if the information recording operation and the printing operation are performed separately as described above, there is a problem that a long time is required every time a new recording disk is created.

  The present invention has been made to solve the above-described conventional problems, and an object of the present invention is to provide a disk drive device capable of simultaneously performing a recording operation on a disk information recording surface and a printing operation on a label surface.

  The object is to rotate the disk in a predetermined direction, an optical pickup device capable of recording information on the information recording surface of the disk, and an optical pickup moving means for moving the optical pickup apparatus in the disk radial direction. A disk drive comprising: an ink jet printing apparatus that performs printing by ejecting ink onto a label surface of the disk; and a control unit that controls the rotating unit, the optical pickup device, the optical pickup moving unit, and the printing device. The apparatus is achieved by a disk drive device in which the control means performs printing on the label surface while recording information on the information recording surface of the disk.

  According to the present invention, since the control means for performing printing on the label surface while recording information on the information recording surface of the disk is provided, the disk drive capable of creating a recording disk in a short time by simultaneously performing information recording and label printing Equipment can be provided.

  Another object of the present invention is to provide a rotating means for rotating the disc in a predetermined direction, an optical pickup device capable of recording information on the information recording surface of the disc, and an optical pickup for moving the optical pickup device in the disc radial direction. Moving means; ink jet printing apparatus that performs printing by ejecting ink onto the label surface of the disk; printing apparatus moving means that moves the optical ink jet printing apparatus in the radial direction of the disk; the rotating means; A disk drive apparatus comprising: a pickup device; an optical pickup moving means; a printing apparatus; and a control means for controlling the printing apparatus moving means, wherein the control means records information on an information recording surface of the disk, With the movement of the optical pickup device, the printing device is moved to follow the printing on the label surface. Also achieved by the disk drive apparatus according to claim Ukoto.

  According to the present invention, the recording apparatus is provided with the control means for performing printing on the label surface while recording the information on the information recording surface of the disc while moving the printing device following the movement of the optical pickup device. It is possible to provide a disk drive device in which printing on the label surface is completed almost simultaneously with completion of writing on the surface. Therefore, it is possible to provide a disk drive device capable of simultaneously performing information recording and label printing to create a recording disk in a short time.

  For example, the control means controls the printer head of the printing apparatus so that the ink adhering to the label surface is arranged at intervals in the circumferential direction of the disk when the disk is rotated once. Alternatively, the timing of ejecting ink from the printer head may be changed, and control may be performed so that printing on at least one line is completed when the disk is rotated a predetermined number of times.

  If the printer head is provided with a plurality of ink nozzles, and the control means drives the plurality of ink nozzles to execute printing on a plurality of lines at the same time, the disc creation time can be shortened. Further, color printing can be performed if the ink nozzles are configured to eject different color inks.

  According to the present invention, it is possible to provide a disk drive device capable of simultaneously performing a recording operation on an information recording surface of a disk and a printing operation on a label surface. With such a disk drive device, a recording disk can be created in a short time while saving the user's trouble.

  Hereinafter, a disk drive device according to an embodiment of the present invention will be described with reference to the drawings. This disc drive device has a function of recording information on the original disc and a function of reproducing information recorded on the disc, and a title, creation date, creator, characters related to these on the label side of the disc, This is a composite device that has the function of label printing images and the like. FIG. 1 is a diagram showing a disk drive device 1 of the embodiment. FIG. 1A is a plan view of the disk drive device 1, and FIG. 1B is a side view of the device. However, in order to make each figure easy to see, there is a portion in which illustration of a part of the configuration is omitted in each figure. This will be clarified in the explanation.

  The disk drive device 1 includes a mechanical chassis 10 serving as a support frame. A spindle motor 11 serving as a rotating means, an optical pickup device 13, and a pair of guide shafts 15 and 16 for guiding the optical pickup device 13 in the disk radial direction are mounted on the mechanical chassis 10.

  A turntable 12 is set on the rotation shaft of the spindle motor 11, and a disk D is placed on the turntable 12. A clamper 18 is disposed above the turntable 12. After the disk D is set on the turntable 12, the clamper 18 is moved downward by a known mechanism (not shown) so as to approach the disk D. The clamper 18 and the turntable 12 are formed of a material that is magnetically coupled, such as steel and a magnet. Since the clamper 18 is magnetically attracted when approaching the turntable 12, the disk D is sandwiched between them with a predetermined pressure. Therefore, when the turntable 12 is rotated by the spindle motor 11, the disk D rotates without being detached from the turntable 12. The clamper 18 is rotatably supported by a structure (not shown), and follows the rotation of the turntable 12.

  As the optical pickup device 13, a device having a conventional configuration can be adopted. The optical pickup device 13 emits laser light corresponding to information to be recorded on the disk D or laser light for reproducing information recorded on the disk D, for example. As a result, information is recorded on the disk D, and the recorded information is reproduced. The optical pickup device 13 includes an objective lens 14 that faces the information recording surface of the disk D. Laser light is emitted through the objective lens 14, and reflected light from the disk D is received. This optical pickup device 13 is designed to be guided by guide shafts 15 and 16 and move in the radial direction of the disk. The optical pickup device 13 is connected to a feed screw 21 rotated by a feed motor 20 via a drive receiving portion 17. That is, the optical pickup moving means is formed by the feed motor 20 and the feed screw 21. Therefore, the optical pickup device 13 can be moved to a desired position in the disk radial direction according to the rotation of the feed motor 20.

  FIG. 1A mainly shows a part related to an original function of the disk drive device, that is, a configuration for recording and reproducing information with the disk D. The above-described optical pickup device 13 is arranged so as to be located below the disk D. That is, the lower surface side (back surface side) of the disk D is an information recording surface, and the upper surface side (front surface side) is a label surface for printing characters, images, and the like. In FIG. 1A, the disk D is represented by a dotted line to facilitate confirmation of the apparatus configuration existing on the lower side.

  FIG. 1B showing a side configuration of the disk drive device 1 shows an ink jet printing device 30 that is not shown in FIG. The printing apparatus 30 is provided on the upper side of the disk D. The printing apparatus 30 includes a printer head 31 having an ink nozzle 32 that ejects ink NK toward the label surface of the disk D. The printer head 31 is connected to a feed screw 36 driven by a feed motor 35. That is, a printing apparatus moving means is formed by the feed motor 35 and the feed screw 36. Therefore, the position of the ink nozzle 32 can be moved in the radial direction of the disk D according to the rotation of the feed motor 35. Specifically, when the disk D is rotated by the spindle motor 11, the printer head 31 of the printing apparatus 30 is moved in parallel with the label surface of the disk D and in the radial direction of the disk, and the position of the disk D in the radial direction and The particulate ink NK is ejected from the ink nozzle 32 according to the peripheral speed of the disk D. The printing apparatus 30 ejects ink NK from the ink nozzles 32 so that a desired character or image is formed on the label surface when the movement from the outside of the disk D to the center side is completed, for example.

  The basic configuration of the present disk drive device 1 has been described above. Further, the disc drive device 1 has a configuration in which when the information is recorded on the information recording surface of the disc D by the optical pickup device 1, printing is simultaneously performed on the label surface by the printing device 30. Hereinafter, this point will be described.

  In general, the disk rotation speed when recording information on the information recording surface of the disk is several times faster than the disk rotation speed when printing on the label surface. On the other hand, there is a limit to the speed and ejection interval at which ink particles are ejected from the ink nozzle 32. Thus, there is a fact that label printing, which requires a slower rotation speed of the disc, has been executed after recording information on the disc. Therefore, it takes a long time to create a new recording disk. Conventionally, when printing one line in the circumferential direction of the disk, the ink particles are ejected from the printer head so that the ink particles are adjacent to each other. Here, since there is a limit to the ejection interval of the ink particles, it is necessary to reduce the disk rotation speed as described above.

  In light of such circumstances, the present inventor has focused on the following points. In inkjet printing, the accuracy required for photographic quality is, for example, 720 dpi, and in the case of characters, for example, 180 dpi. At this time, the size of the dots (attached ink) formed on the label surface is about 35 μm (corresponding to 720 dpi) to 140 μm (corresponding to 180 dpi) depending on the diameter of the ink ejected from the ink nozzle. By the way, in a general disk, tracks are formed in a spiral shape, and the pitch between adjacent tracks is about 1.6 μm. Here, the optical pickup device performs an information writing operation along a spiral track.

  Examining the above situation, if the track pitch is 1.6 μm, the 35 μm dots will straddle about 21 tracks, and the 140 μm dots will straddle about 87 tracks. .

  In the past, the first ink particle A1 was ejected to form the dot a1 on the label surface, and the next ink particle A2 was immediately ejected to form the dot a2 near the dot a1, so the disk was rotated. It seems that it was necessary to slow down the speed. However, from the above analysis, in the case of a 35 μm dot corresponding to 720 dpi, all dots need only be formed on the same line (circle) as the dot a1 exists while the disk rotates about 21 times. FIG. 2 is a diagram schematically showing how dots are formed on one line L1 (first line L1) of the disk D. As shown in FIG. For example, in the first round of the disk D, dots a1, a2, a3,... Are formed at intervals, and in the second round, dots b1, b2, b3,. All the dots on the first line L1 may be formed while the disk rotates at the number of rotations corresponding to the number of tracks straddling (21 to 87 in the above example). When printing on the first line L1 is completed, dots may be similarly formed on the adjacent second line L2.

  As is apparent from the above description, when the drive of the printing apparatus 30 is controlled so that ink (dots) that adheres to the label surface when the disk D is rotated once is arranged at intervals in the circumferential direction, 1 of the disk D Since the number of ink ejections per rotation can be reduced, printing can be performed without reducing the rotational speed of the disk D. That is, it is possible to perform printing at a substantially increased processing speed. The disk drive device 1 of the present embodiment is based on the above technical idea, and moves the printing device 30 so as to follow the movement of the optical pickup device 13 to transfer information to the information recording surface of the disk D. Print on the label surface while writing. Therefore, according to the present disk drive device 1, the creation time of a newly created recording disk can be greatly shortened compared to the prior art.

  FIG. 3 is a block diagram showing an electrical configuration of the disk drive device 1. As described above, the disk drive device 1 includes the spindle motor 11 that rotates the disk D in a predetermined direction (clockwise in FIG. 1), the optical pickup device 13 that records and reproduces information on the disk D, and the optical pickup device. 13 includes a feed motor 20 that moves the disk 13 in the radial direction of the disk, a printer head 31 that includes ink nozzles 32 that eject ink toward the label surface of the disk D, and a feed motor 35 that moves the printer head in the radial direction of the disk. Yes. These are controlled entirely by a CPU (Central Processing Unit) 40 serving as control means. The CPU 40 is configured around a microcomputer, and is connected to a RAM (Random Access Memory) 42 and a ROM (Read Only Memory) 43 via a bus 41. Various programs executed by the CPU 40 are stored in the ROM 43. The RAM 42 provides a work area when the CPU 40 executes a program. CPU40 calls a program suitably and performs required control.

  The CPU 40 moves the optical pickup device 13 in the radial direction of the disk while driving the spindle motor 11 and the feed motor 20, and performs a series of controls for recording and reproducing information on the disk D. At this time, the CPU 40 controls the printing on the label surface of the disk D while controlling the feed motor 35 so that the printer head 31 moves following the optical pickup device 13.

  The CPU 40 controls the timing of ejecting ink onto the label surface according to the rotational speed of the spindle motor 11 and the position of the printer head 31 in the disk radial direction. For example, the CPU 40 first grasps the position of the printer head 31 relative to the disk D from the driving speed of the feed motor 35 that defines the rotational speed of the spindle motor 11 and the radial position of the printer head 31. Next, ink ejection data for ejecting ink from the printer head 31 is created based on the print data supplied to the printer head 31. As described with reference to FIG. 2, the ink ejection data ejects ink so that dots are arranged at intervals for each rotation of the disk D, and printing of one line is completed when a predetermined rotation occurs. To do. The CPU 40 creates ink ejection data for each line at the radial position, and sequentially prints by moving the printer head 31 in the disk radial direction while following the optical pip-up device 13. When the printer head 31 is moved from the outside to the inside or from the inside to the outside to reach the end position, printing of characters and images is completed at a predetermined position on the label surface.

  As described above, when one dot is formed on the disk, a large number of tracks are straddled. Therefore, the movement control of the printer head 31 can be reduced as compared with the frequency of controlling the movement of the optical pip-up device 13. Therefore, it is sufficiently possible to move the printer head 31 following the optical pip-up device 13. When the printer head 31 is made to follow the optical pip-up device 13 in this way, printing on the label surface by the printer head 31 is performed almost simultaneously with the completion of the writing of information on the information recording surface. Can be completed. In this way, the present disk drive device 1 can perform printing on the label surface in a short time.

  FIG. 4 is a flowchart showing an example of a routine for printing on the label surface when the CPU 40 records information on the disk D. The routine shown in FIG. 4 enters a standby state when the disk drive device 1 is powered on, for example. When the CPU 40 starts recording information on the disk D (S101), the CPU 40 controls the feed motor 35 to move the printer head 31 to the printing position (S102). Further, the CPU 40 confirms the rotational speed of the disk D based on the control to the spindle motor 11 (S103).

  Here, the CPU 40 creates ink ejection data from the print data supplied to the printer head 31 (S104). In this ink ejection data, as described above with reference to FIG. 2, dots are arranged at intervals on a line on the label surface. The CPU 40 ejects ink at a timing set based on the ink ejection data (S105), and moves the printer head 31 to follow the optical pickup device 13 (S106). When the printer head 31 reaches the end position (S107), writing on the information recording surface is completed. At this time, printing of characters, images, etc. is completed at a predetermined position on the label surface, so the processing according to this routine ends. .

  As described above, the disk drive device 1 can write information on the disk D and print on the label surface almost simultaneously. Therefore, since a recording disk printed on the label surface can be created, the user's trouble can be saved. In addition, since the printing is performed so as to correspond to the rotation speed when information is recorded on the disk D, the required time can be shortened.

  FIG. 5 is a view showing a modification of the disk drive device. The same components as those of the disk drive device 1 shown in FIG. In FIG. 5A, a printing apparatus 30 having a color printing function is provided. In addition to the black ink ink nozzles, the printer head 31 is provided with a total of four ink nozzles 32, three for cyan, magenta, and yellow. By using such a printer head, color label printing can be performed. In the example shown in FIG. 5A, the position of each ink nozzle is different in the disk radial direction, so color printing on a single line may be performed by moving the position of the pre-head 31.

  FIG. 5B shows another modification. The disk drive device described above has a configuration for moving the printer head, but is not limited to this configuration. FIG. 5B shows a disk drive device in which the printer head 31 is arranged at a fixed position and includes a large number of ink nozzles 32 so that the label surface can be printed at once. With such a configuration, printing on all lines is completed when the disk is rotated a predetermined number of times, so that printing can be performed in a very short time.

  In the disk drive device of the above-described embodiment, when recording on the disk D, there are cases where the track linear velocity is constant and the rotation speed of the disk D is constant. Can also handle cases.

  The preferred embodiment of the present invention has been described in detail above, but the present invention is not limited to the specific embodiment, and various modifications can be made within the scope of the gist of the present invention described in the claims.・ Change is possible.
